Pulse Mode sweeps (Model 2430 only)
When performing a sweep with the Model 2430 in the Pulse Mode, each step or
point of the sweep is made up of a pulse period. In general, a pulse period con-
sists of the pulse width (output on-time) and the output off-time. Figure 10-5
shows an example of a 3-step linear staircase sweep for the Pulse Mode (start =
1V, stop = 3V, step = 1V). A measured reading is performed for each of the three
pulse steps. Readings are not performed for the output off-times.
For normal (DC Mode) sweep operation, the time duration spent on each step
consists of the set source delay and the time it takes to perform the measurement.
For the Pulse Mode, source delay is not used. The pulse width consists of the
pulse width delay, internal overhead time and the pulse signal measurement. The
output off-time typically consists of zero and reference measurements (used to
calculate accurate pulse readings), internal overhead time, and an optional pulse
delay.
